[0002] As an important part of the power system, the operation status of the substation directly affects the stability and security of the power grid. In order to ensure the normal operation of the substation, it is necessary to monitor and automatically accept the monitoring information of the substation in real time. The automatic acceptance technology of the substation monitoring information is mainly realized by quickly comparing the automatic acceptance device with the automatic acceptance process of the centralized control main station. This technology can accept a signal in a very short period (about 0.5 seconds), greatly reducing the time and error of manual acceptance and improving work efficiency; However, this acceptance technology has the following problems. First, since the automatic acceptance process is very fast, manual intervention and verification cannot be performed, so there may be some errors that cannot be discovered and corrected in time; Second, the existing acceptance technology lacks a method for automatically accepting the correctness of the association of the light-emitting sign, and does not meet the requirements of the "New Generation Substation Centralized Monitoring System Acceptance Management Specification (Trial)"; These problems limit the application scope and use effect of the existing technology, and need to be further improved and perfected; Therefore, it is very necessary to provide an intelligent acceptance system for light-emitting sign based on image recognition and signal automatic triggering, which has an automatic trigger function, a graphic capturer to capture pictures at regular intervals, and automatic verification of cascade accuracy. Summary of the invention
